This invention relates to outlet valves of the type which are applied to or mounted on the delivery spouts of water faucets for the purpose of controlling the outflow of water at that part of the faucet. t is particularly intended and adapted for controlling the delivery of water for washing and rinsing f dishes and other tableware.

Among the objects of the invention are to provide in such a valve means by which eithera spray of water or a copious discharge may be delivered at will; to provide means whereby the valve may be held in position for delivering either a spray or copious supply of water for an indefinite time without the attention of the operator; and to enable a rinsing spray to be .delivered while pressure is maintained on a controller by a persons hand or by a dish held in the hand and automatically shut off when such pressure is discontinued. Other objects are concerned with structural features and connecting means described in the following specification and illustra-ted in the accompanying drawings.

Like reference characters designate the same parts wherever they occur in all the figures.

The valve includes a body or casing I5 which is connected to the faucet extremity by any one of a variety of means later described, and has an entrance opening at the end which is placed next to the faucet and a delivery spout I6 at the opposite end. It contains an internal annular shoulder I1 provided with a seating face on the upper side of its margin against which a valve body or element i8 is normally seated.

This valve body may be called the main valve. It has a passage through it with a valve seat at the upper end on which a secondary valve I9 is adapted to bear, and normally bears, for closing the passage.

lPreferably the main and auxiliary valves are combined in a unit assemblage. A suitable construction of such an assemblage is shown in Fig. 2. Here the main valve element I8 is a disk of suitable material, which may be metal, rubber composition, ber, etc. It is made with a central opening in which is contained a tube 20 having a ange 2I at its lower end underlying the valve element I8, and its upper end protrudes above the Valve element and is externally threaded. A perforated dome 22 enveloping the secondary valve I9 is screwed on the threaded end of tube 20 and has a peripheral flange 23 overlying the upper side of valve disk I8. The latter is rmly clamped between the flange 2I and the dome. Valve I9, which is preferably a ball, is confined within the perforated dome or cage 22, and seats against a seating surface formed in the upper end of the tube or sleeve 20. Both valves are normally held in closed position by gravity and by the pressure of water existing in the faucet spout when the valve which admits water to the faucet is open. y

It may be noted here that the faucet spout 211 shown in Figs. 1 and 2 is of a type commonly installed in relation to dish washing sinks, swiveled to a fixture which is connected with both hot and cold water pipes, each of which is controlledby its own valve. Such spouts are com'- -monly formed with a marginal bead 25 at their outlet end, and the coupling shown in Figs. 1 and 2 by which the valve casing is attached to the faucet is designed forV accommodation to spoutsof this type.

The coupling consists of a tube or sleeve 26 having an internal shoulder 2l at one end and being internally threaded at the opposite end to engage external threads 28 on the valve casing I5. The diameters of the sleeve 26 and of the space within the shoulder 2l are large enough to permit the sleeve to be passed over the terminal bead 25 and around the bend of the spout which is located a short distance above the extremity. A rigid washer 2S is located within the sleeve 2E abutting against the flange 21 and has an internal diameter which is smaller than that of the shoulder 21 but large enough to pass over the bead 25. A packing ring B of rubber coinposition or other suitable elastic, flexible and Water impervious material is placed toV surround the extremity of the faucet and project from the end thereof. It lmay be formed with an internal groove to receive the bead 25 and with internal diameter smaller than that of the bead at each side of the groove. It is stretched in being applied to the faucet. Sleeve 26 an'd "washer 29 "are slipped back over the faucet spout to. leave the extremity thereof clear for application 'of the packing ring, and are afterwards `slipped forward so that the end of the sleeve protrudes beyond, The valve Y'easing the extremity of the spout. is then screwed into the sleeve sufficiently to compress the packing ring between the end 'of the casing l5 and the washer 29 and holdlit Vin tight supporting engagement 'with the faucet and sealing contact therewith and Ywith the valve casing.

The Vsecondary valve {'9 fcan be opened independently, and bothvalves opened together, by a valve operating lmember or actua-tor which, in the embodiment novv` being described, 'consists of a ring Btl having Vtwo or 'more lradial arms 3-I joined to a central hub 32, and a tube 3'3 secured to the hub. r)She ring 30| surrounds the vvalve casing l5 and is preferably provided with a cushion 34, which -rn'a-y be a ring 'of frubber composition in which a flange on lthe actuator ring 334 is embedded, substantially as shown. Arms 3| are spaced substantially "'equiangularly around vthe cen-ter of the actuating rin'g and pass through inclined slots Vin the Sides of the casing l5; such slots being related to the arms in such man- 'ner that fall "of the larms can vbe placed at the -lower :ends of their respective slots fat the y'saine time and are 'then supported stably 'with the plane `of the actuator ring perpendicular to the axis vof the Valve casing.

When the actuator is in Athe Vpositionla'st menhoned, thefhub 32 is spaced a short distance :below'the vlia-nge 2I which underlies the 'main valve tbody 18. Tube 33 Vextends `through this hub vand its upper end 'passes 'through the bore Aof Y'tube y20 with suflicientclear'ance lto be capable of r'noving freely therethrough and to avoid binding if it is somewhat inclined when being raised. The upper end -of the tube terminates 'so close =to the underfsideiof Athe secondary valve 'element I9 that it will unseat the valve when raised by even a slight distance. In the 'side walls-of the tube at the `upper end vare notches which act to lbreak up water flowing when the secondary valve is Vunseated so that the water/issues from the ltube 'as a spray. W hatwater thenflows through the ananular space `around tube V33 in the bore vof the ytube-2l! strikes the hub 32 and is also broken into aspray.

When the actuator tube 'is'rotat'ed theu'nder facesof the inclined slots 35 cause itto'be raised y with the effect, rst of unseating Athe secondary valve -I 9; and then, if the movement iis continued far enough, of unseating the main valve I8. 'Engagement of `the hub 32 with the flange 2| and kcontinued upward movement thereafter causes 'thefrnain valve to be unseated. A

`'Shallow notches -36- yand 31 are formed lin vthe 4bottom edge of Veach inclined slot 35 'at -an intermediate point fand `lat fthe upper fend respecretain the actuator ring in the position where it holds the secondary valve I9 open but does not open the main valve; while the notches 31 retain it at a high enough elevation to hold the main valve open. Thus the actuator may be placed, and left Without further attention, in position for causing either a spray of water to pass through the main Valve, or a copious now of water to pass around the main valve. When the actuator rests at the low end of the slots, it may be lifted, Without rotation, by upward pressure of a persons hand, or pressure exerted Vthrough a dish held in the hand enough to open the secondary valve `only for emission of a spray, and the slot is Wide enough to permit this action. When Athe pressure is relaxed, the water is jjautomatically shutoff. Thus a dish washer can take a dish from a sink or pan containing soapy water and, by pressing upward with his hand or the dish on the cushion ring 34, cause the dish to be rinsed by a spray of clean hot water.; and this Without either turning the faucet valve handle or wasting lhot water. But when a continu ous spray is required, this can be obtained by turning` the actuator so that its arms occupy the notches 36. Similarly a full stream for filling a sink or dish pan can be caused to emerge by turning Ythe actuator into engagement with the notches 31.

In order to permit vassemblage of the actuator with the valve 'casing Yin the relation shown, the bottom of the valve casing is preferably made as a separate piece 38 in the form of a cap which is screwed on the main part of the casing and in which the outlet opening I6 is formed. The slots 35 are formed with downward extensions through the bottom edge of the casing body, through which the arms may be passed. Cap 38, being then screwed in place, closes and obstructs such slot extensions.

AAll of the parts 'of this attachment, except the packing ring 36, cushion or buffer 3ft and possibly the main valve element I8, are made of metal or any other suitably rigid and durable material.

A variation of means Yfor securing the outlet valve -to the faucet, which can be substituted for that above described, is shown in Figs. 5 and 6. Here `anurnber of annular segments 39 of hard ber or other suitable material are placed around the Aend of the faucet. Theyh'ave a torio internal curvature shaped to t more or Vless closely the `circumference of the tube and the curve at the upper side of the bead 25. Collectively theylsub- -stantially encircle the faucet terminal, as shown by Fig. 6. A'rabbeted shoulder 4) is formed in the upper side 'of the .segments to receive the ange 21 of the tube or sleeve 26. A compressible Washer 4l is located between 'the opposed Vend surfaces ofthe faucet and valve casing l5. The shoulders 46 serve -a's abutments against which the sleeve .reacts 'when forcing the 'valve casing against the faucet to compress the washer 1H. Thesegrnents are applied to the'faucet when the sleeve 26 is 'pushed back and 'are held in place by a-spring-ring 42 which'is slipped intoan encircling external groove of the segments. Or Van --elastic band can be placed in the groove instead ofthe fspring ring shown. "Such ring or band --holds Tthe segments in place until rthe coupling sleeve -is vpassed over 'them and screwed on the valve casing. 'Thereafter the-sleeve'confines the segments and-causes them Ito bind closelyagains't the faucet bead.

Another 'vaiiation of coupling means 'is shown 29 are substantially the same as those first described. But instead of the packing ring 30, a ring a which does not extend under the end of the faucet is used. A rigid ring or washer |42 is placed on the valve casing underneath the packing ring, and the latter is compressed between the washers 29 and |42 when the coupling and Valve casing are screwed together, and is thereby `brought into binding engagement with the faucet ternal shoulder 44 between which and the extremity of the faucet a compressible washer 45 is coniined.

The principles of the invention can be embodied in other structural forms and combinations than that before described. One of such other embodiments is shown in Figs. 9l3. Here the main valve body |8a is avdisk seated on the upper side of a base plate 46 and having a tubular stem 41 which iits rotatably in a central bearing passageway in the base plate 46 and projects beyond the under side of the base plate. A number of ports 48 in the disk and ports 49 in the tubular stem 41 are adapted to be placed in and out of registry with passages 50 in the base plate,

by partial rotation of the valve body. The passages 50 open at one end in the surface on which the valve disk is seated, and at the other en'd in the sides of the passageway through the base plate and are suitably located for simultaneous registry with the ports 48 and 49.

The secondary valve |9a is the integral conical head of a stem 5|, which extends and is slidable endwise through a guideway 52 in the center of the main valve; this guideway and the stem 5| being separated from the walls of the main valve stem 41 by an annular space wide enough to permit unimpeded flow of water when the ports 48 and 49 are placed in registry withl the passages 50. Transverse passages 53 extend inward through the sides of the valve head |9a into intersection with a longitudinal passage 54 in valve stem 5|, which extends from the point of intersection to the lower end of that stem. Valve |9a seats in a recess in valve |8a which is deep enough to close the outer ends of passages 53 when valve f flow through the passage 54 with a whirling motion andemerge therefrom as a spray.

A ring 55 is secured, as by means of screw threads, to the end of the main valve stem 41 at a suitable distance from the under side of base plate 46. This ring supports three or more wedge members 56 on its upper side. A cup-like member 51 having numerous perforations in its bottom portion is secured tightly to stem 5| and is provided with side walls which embrace the ring 55 and lugs 58 extending from the upper edges of the side walls over the ring. Such lugs are equal in number, and are spaced equally, to the wedge members 56 and are so disposed that. when the cup 51 is rotated in one direction, they will ride up and pass over the wedge members, as shown by Figs. 11, 12 and 13. One of the lugs 48 has a downwardly extending tongue 59 projecting into a notch 60 in the ring 55. Preferably a housing 6| of rubber composition or other suitably yielding material is applied to the cup member 51 to surround the same. Itis fashioned with a flange 63 to overlie the lugs 58, and is further fashioned into the form of a spout 62 below the perforated bottom of the cup 51 to conne outflowing water within desired limits. This cup is the means for operating the valve elements and will at times be designated the valve actuator. The spacing of the' ring 55 from the base plate, the height of the wedge members 56, and the thickness of the lugs 58 and overlying ange 63 of the housing 6|, are established with such values that, when the cup member 51 is raised by the wedge members, flange 63 is brought against the base plate to form a Water seal. Rise of these parts to the extent indicated also raises the secondary valve |9a enough to permit water to flow through the passageways therein.

Notch 60 is Wide enough to permit; rotation of the valve actuator to raise the secondary valve without turning the main valve, as is apparent from Figs. 1l and 12. Further movement in the direction of the arrows applied to Figs. 12 and 13 rotates the mainv valve and may be continued far enough to bring the ports 48 and 49 into registry with the passages 50. A stip pin 66 mounted on the base plate in a notch 61 of the valve disk |8a limits the rotation of this disk at points wherein the ports and passages are, respectively, in full registry and wholly occluded. The auxiliary valve can be opened also by upward movement of the actuator eifected by pressure applied to the spout 62 or to any other part of the actuator.

This last described form of valve can be attached to a faucet by various means, for instance, any of the couplings previously described, and is here shown as attached by a duplicate of the coupling illustrated in Figs. 5 and 6. It is not essential that the part herein described as the base plate 46 be a substantially flat plate, for it could be variously formed provided only that it is capable of mounting the valve members in substantially the relationship here shown. That is, the base 46 or its like can be made with walls extending axially from its margin more or less like the side walls of the casing I5 shown in any of Figs.

2, 7 and 8 above the internal shoulder I1. In all of the forms precedently described, the casing |5 is essentially a base member having a passageway for Water and a seating surface for a main valve.
